In order to avoid the crypto++ mess, the code uses the Windows Cryptography API,
which is standard. There is also some makefile magic to cross-compile:
make PREFIX=i686-w64-mingw32- EXE_EXT=.exe
I selected the option so that it should statically link supports libraries used
by gcc (slsj and libwinpthread).

The new code supports reading and writing UPG files. I kept the old keysig
search code but it only supports the old format (the new format has too long
keys anyway). Since we now have to support two types of encryption(DES and AES),
I reorganized the crypto routines and clean-up some code.

We already use Crypto++ for DES anyway, and using OpenSSL is not great because
of its incompatible licence.
